Quad Hook
A DIN 15402C Quad Hook (also known as a four-prong hook) is a heavy-duty lifting component engineered to German industrial standards (DIN) for use in demanding crane applications. Typically used for very heavy lifts, ranging from 160 tons up to 4000 tons, with equalized loads on all four prongs.
– Hook, nut and crosshead forged, heat treated and thread fully machined as per DIN15403 design
– Material: super alloys
– Mechanical properties: V
– Load test: requested/recommended after machining
– Certificate: EN10204-3.1
– Standard: DIN 15402-C
features:
- Four-point balanced loading — evenly distributes load gravity, preventing cargo slippage and tipping
- Integral forging — one-piece construction for maximum strength and reliability under extreme loads
- High-strength alloy steel — typically grades V / W, safety factor ≥ 4:1
- Rounded horn tips — minimize surface damage to cargo
- Capacity range — 160 t to 4,000 t (equal load on four prongs)
- Standard — DIN 15402-C
Quad hooks are engineered specifically for extra-large tonnage loads requiring multi-point balanced lifting. Typical applications include:
- Steel & metallurgy — ladles, ingots, large slabs, rolling-mill equipment
- Heavy machinery assembly — generator stators, turbine rotors, transformers, pressure vessels
- Large structural lifting — bridge girders, offshore modules, TBM components
- Floating cranes & offshore — heavy rigging on floating cranes
- Ports & shipbuilding — hull sections, marine engines, heavy port equipment
